Dual-GPU Workstation Card

The NVIDIA GRID K520 is a professional graphics card built for virtualised desktop and compute workloads. It integrates two GK104 processors on a single board, each with 1,536 shading units and 4 GB of dedicated memory. The card targets IT departments deploying high-density remote workstations or render nodes.

Passive Dual-Slot Design

A dual-slot cooler handles the 225 W board power through a single 8-pin connector. The 267 mm length fits standard server chassis, while the PCIe 3.0 x16 interface supplies system bandwidth. No display outputs are present because the GPU is engineered for headless operation in virtualised environments.

Upgrade From Single-GPU Boards

The twin-GPU layout doubles shading and memory resources compared with single-processor cards of the same era. The jump is worthwhile when user density or frame-buffer demand exceeds what one GK104 can deliver. Buyers needing monitor connectivity or consumer driver features should look elsewhere.

Questions about this item

What does the PCIe 3.0 x16 interface cap in practice?

The card uses a PCIe 3.0 x16 slot for host communication, while each of the two GK104 GPUs runs its 4 GB frame buffer over a 256-bit GDDR5 link at 5 Gbps.

What physical space and power connections does the card require?

It occupies two slots, measures 267 mm long, and draws up to 225 W from a single 8-pin power connector.

How is the GRID K520 installed, and what step is often missed?

Seat the card in a PCIe 3.0 x16 slot, attach the 8-pin power cable, and note that no display cables are needed — the card has no video outputs and is managed remotely.
